Make the most of your cauliflower (spring) harvest with careful short term storage and preparation.

Spring cauliflower florets arranged on a tray for freezing

Freezing Cauliflower (Spring)

General preservation or storage guidance

Preparation About 25 minutes active, plus cooling and freezing

Cauliflower florets freeze well for cooked dishes when blanched briefly, cooled promptly and packed with room for expansion.

Method

  1. Choose a fresh, firm spring cauliflower. Remove leaves, rinse the head and divide it into even florets about 2.5–5 cm (1–2 in) across.
  2. Blanch the florets in boiling water for 3 minutes. Use batches small enough for the water to return to a boil promptly.
  3. Drain and cool immediately in cold water until thoroughly chilled; drain well again.
  4. Pack into freezer containers, leaving about 1.3 cm (½ in) headspace. Seal, label and freeze promptly.
  5. Use from frozen in cooked dishes. Keep continuously frozen and do not refreeze after thawing.

Storage

Freezer at −18°C or colder · Keep continuously frozen; no exact quality period stated

Spring cauliflower florets preserved in a glass jar

Pickling Cauliflower (Spring)

General preservation or storage guidance

Preparation About 1 hour active, plus jar processing and cooling

This tested sweet-sour cauliflower pickle uses a measured 5% vinegar mixture, pre-cooks the florets and is processed in a boiling-water canner.

Method

  1. For about nine half-pint jars, measure 12 cups (about 2.8 L) of 2.5–5 cm (1–2 in) cauliflower florets, 4 cups (950 ml) white vinegar labelled 5% acidity, 2 cups sugar, 2 cups thinly sliced onion, 1 cup diced sweet red pepper, 2 tbsp mustard seed, 1 tbsp celery seed, 1 tsp turmeric and 1 tsp hot red-pepper flakes.
  2. Wash the cauliflower, remove stems and blemished parts, and separate into even florets. Boil the florets for 3 minutes in water containing 4 teaspoons canning salt per US gallon (3.8 L); drain and cool.
  3. In a large pan combine the measured vinegar, sugar, onion, red pepper and spices. Bring to a boil and simmer for 5 minutes.
  4. Distribute onion and pepper among prepared jars. Fill with florets and hot pickling liquid, leaving 1.3 cm (½ in) headspace; remove air bubbles, wipe rims and fit lids.
  5. Process hot half-pints or pints in a boiling-water canner for 10 minutes up to 305 m (1,000 ft), 15 minutes from 306–1,829 m (1,001–6,000 ft), or 20 minutes above 1,829 m (6,000 ft). Follow the NCHFP process and altitude table exactly.
  6. Cool jars undisturbed, check seals and refrigerate any unsealed jar. Store properly processed sealed jars cool and dark; refrigerate after opening.

Storage

Cool, dark storage for properly processed sealed jars; refrigerate after opening or if unsealed · Follow the tested NCHFP recipe; no additional shelf life is claimed
